GYNECOLOGICAL INSTRUMENT.

SPECIFICATION-forming part of Letters Patent No. 597,988, dated January 25, 1898.

` Application na nnen, 189e. serai No. 595.207. oa maan To a/ZZ whom it may concern:

Beit known that we, EMIL KRNING and ED- MUND BENSEL, subjects of the King of Prussia, Emperor of Germany, and residents of Magdeburg, Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Gynecological Instruments, of which the following is a specification.

This invention has for its object to provide a new and improved gynecological instrument particularly designed for introducing medicaments into natural channels of the human body which require to be subjected to medical treatment.

To accomplish this object, our invention consists in Athe features of construction and in the combination or arrangement of parts hereinafter described and claimed, reference being made to theaccompanying drawings, in which- Figure 1 is a longitudinal central sectional view of our improved instrument, showing the pivoted jaws in their closed position; and Fig. 2 is a similar view showing the jaws spread open.

In order to enable those skilled in the art to make and use our invention, we will now describe the same in detail, referring to the drawings, wherein- The letter a indicates a tube connected at one extremity with an atomizing-bulb b for introducing medicine in a powdered state.

.The opposite extremity of the tube is provided with a uniformly-perforated spherical nozzle or rose c 'for the distribution of the medicine used. Around this nozzle 4or rose a number of radially-separating levers d are grouped, each lever engaging by means of a outer end of a sleeve g.

by means of an internally-screwed socket o, Awhich is revolubly mounted upon the sleeve g and can be screwed forward and backward upon a corresponding screwed enlargement be moved longitudinallyA d p of the tube a.. The socket lo when rotated carries the sleeve g along with it. In the device illustrated an india-rubber or other elastic ring e', having the tendency to always force the separating-levers into the closed position, is arranged in suitable grooves lm., provided near the inner edges of the levers.

When the sleeve g is moved outward or in a direction toward the nozzle or rose o, the conical shoulders cl2 act against the nozzle or rosein such manner that the levers are spread outward, as represented in Fig. 2, to secure an enlargement of the organ to be treated and thus obtain the eiiicient introduction and distribution of the medicaments employed. When the sleeve g is moved inward or in a direction away from the nozzle or rose, the elast-ic ring e forces the levers toward one another to the position represented in Fig. l, in which position of the parts the instrument is readily introduced.

As hereinbetore indicated, the instrument is principally intended to serve for the introg duct-ion of medicaments into the vagina. The apparatus is. not, however, restricted to this special use, but may be employed in all instances where natural channels of the human body are required to be subjected to medical treatment. In this latter respect dimensional modifications might be required. Moreover, the invention would not be materially altered if, instead of the atomizing-bulb, an analogous means-for example, a syringewere connected to the apparatus. In this case the apparatus may also serve for the injection of liquids. The number and shape of the separating-levers may of course be variable, being dependent upon the requirements of the special purpose for which the instrument is to be used.

l. A gynecological instrument for intro ducing medicaments into natural channels of the human body, consisting of aninner tube provided at its endwith a bulbous nozzle, an exterior sleeve movably arranged on said tube, a series ot' levers pivotally mounted on the sleeve and having conical shoulders which bear against the bulbous nozzle, means for drawing the levers against the bulbous nozzle, and screw-threaded devices at the inner ends of the tube and sleeve for adjusting IOO ,i is

said sleeve longitudinally on the tube to expand the levers over the bulbous nozzle, substantially as described.

2. A gyneeologieal instrument for introducing medicaments into natural channels of the human body, consisting of an inner tube provided at its end With a bulbous nozzle, au exterior sleeve movably arranged on said tube, a series of levers pivotally mounted on the sleeve an d having conical shoulders which bear against the bulbous nozzle, a spring for drawing the levers against the bulbous nozzle, and screw-threaded devices at the inner end of the tube and sleeve for adjusting said sleeve longitudinally on the tube to expand the levers over the bulbous nozzle, substantially as described.

3. A gyneeologioal instrument for introducing medicaments into natural channels of our invention We have signed our naines, in 3o presence of two Witnesses, this 4th day of May, 1896.
